That's the issue though, Launchbox is closed source, and also only has two devs, which means time and resources are a issue, for what is a limited audience, who are also used to getting things for free. I'm sure if Launchbox was made for Linux the basic program would still be free, and you pay for Premium and BIgbox, as is currently the case, and you would want to be using Bigbox on a device like the Steamdeck
